How we can price(calculate cost) garbage collection in different municipals of a city? These municipals in a city are out-sourcing all garbage collections using contracts with different companies. The municipals doesn't know real cost for contract of a year of own area and we need estimate it.
Currently companies offering their costs to municipals. for example we need 100 working sweeper, 20 cars for garbage collection etc. and total cost is N. But we need estimating to obtain real total cost for every area for better negotiating (preferably using simple and understandable methods). what do you suggest?
* We only want focus on municipals not households because households aren't directly paying garbage collection costs.
Thanks.
